Two-dimensional (2D) materials have attracted tremendous interest as fluorescence quenchers of dye-labeled biomolecules for application in biosensing. Metal-organic framework (MOF) nanosheets, as a new type of 2D material, have rarely been studied as bioanalytical platforms. Herein, we synthesize a series of ultrathin lanthanide-based MOF (MOF-Ln) nanosheets as a dye-labeled aptamer platform. T...
The excellent sorption kinetics, reversibility, and guest-induced changes in the MOF structure and/or properties make them intriguing candidates, in particular, for sensing. However, only a few of these changes (mainly luminescence quenching) have been explored for sensing purposes due to their small magnitude or the diffi culty in their measurement. Integrating MOFs into devices will allow the...
To design high-internal-phase emulsion (HIPE) systems is of great interest from the viewpoints of both fundamental researches and practical applications. Here we demonstrate for the first time the utilization of metal-organic framework (MOF) for HIPE formation. By stirring the mixture of water, oil and MOF at room temperature, the HIPE stabilized by the assembly of MOF nanocrystals at oil-water...
BACKGROUND In a recent intervention study, the daily supplementation with 200 mg monomeric and oligomeric flavanols (MOF) from grape seeds for 8 weeks revealed a vascular health benefit in male smokers. The objective of the present study was to determine the impact of MOF consumption on the gene expression profile of leukocytes and to assess changes in DNA methylation. METHODOLOGY/PRINCIPAL F...
Controlled ripening of climacteric fruits, such as bananas and avocados, is a critical step to provide consumers with high-quality products while reducing postharvest losses. Prior to ripening, these fruits can be stored for an extended period of time but are usually not suitable for consumption. However, once ripening is initiated, they undergo irreversible changes that lead to rapid quality l...
The molecular building block approach was employed effectively to construct a series of novel isoreticular, highly porous and stable, aluminum-based metal-organic frameworks with soc topology. From this platform, three compounds were experimentally isolated and fully characterized: namely, the parent Al-soc-MOF-1 and its naphthalene and anthracene analogues. Al-soc-MOF-1 exhibits outstanding gr...
BACKGROUND Among the very elderly, poor oral health reduces life expectancy. In this study, differences in the magnitude of the maximum occlusal force (MOF) in the very elderly were examined in terms of effects on all-cause mortality in a 3-year follow-up. METHODS We evaluated 489 community-living elderly individuals aged 85 years or older. MOF was measured using an occlusal force measuring d...
BACKGROUND It has been suggested that severity of the immune response induced by immune cells is associated with morbidity and mortality from acute pancreatitis. The authors investigated and evaluated the relationship between distinct peripheral lymphocyte subsets at admission and clinical outcome prior to hospital discharge so as to find a predictor to the prognosis of acute pancreatitis in ly...
HYPOTHESIS Abdominal compartment syndrome (ACS) is a morbid complication of damage-control laparotomy. Moreover, the technique of abdominal closure influences the frequency of ACS. DESIGN Retrospective cohort study. SETTING Urban level I trauma center. PATIENTS We studied 52 patients with trauma who required damage-control laparotomy during the 5 years ending December 31, 1999, and who su...
در این مطالعه، ترکیب شبکه آلی فلزیmof-199 به عنوان جاذب گاز هیدروژن بر اساس روش جذب سطحی به کار گرفته شد. نانو ساختار به دست آمده با نانوذرات پالادیم کاهش داده شده بر روی نانولوله های کربنی تک دیواره، به منظور افزایش ظرفیت جذب هیدروژن در دمای محیط اصلاح شد و سپس ترکیب اصلاح شده به وسیله روش های bet ،sem ،xrd و tga شناسایی شد. میزان ظرفیت جذب هیدروژن بر روی ترکیب سنتز شده با روش حجم سنجی در دمای...
